Summary: Kernel maps only one page of FDT. When FDT is more than one page in size, data TLB miss occurs on memmove() when FDT is moved to kernel storage (sys/powerpc/booke/booke_machdep.c, booke_init()) This introduces a pmap_early_io_unmap() to complement pmap_early_io_map(), which can be used for any early I/O mapping, but currently is only used when mapping the fdt.
